PURPOSE:To facilitate the arrangement work of a detection element and to simplify the structure, by providing the first square pillar-shaped load detection part and the second thin plate-shaped load detection part. CONSTITUTION:A columnar load detection part 11 is connected to a load transmitting part 10 on which a load acts. This columnar load detection part 11 is a columnar body having a square cross-section and parallel plate structures 12, 13 are constituted to the columnar body. Strain gauges S31-S34, S11, S12...S21, S22... are adhered to the parallel plate structures 12, 13. A ring-shaped load transmitting part 15 is provided facing the load transmitting part 10, and a load detection part composed of a thin plate 17 is provided between a circular column 16 connected to the end part of the columnar load detection part 11 and the load transmitting part 15. Strain gauges Sa1-Sa4, Sb1-Sb4, Sc1-Sc4, Sd1-Sd4 are adhered to the thin plate 17.
